7.3    Switching to another database, or creating a new one

       To change databases from within BlueBook, click File.
       This brings up a floating panel with four options:  Next,
       Backup, Text, and Erase.

       Click Next, and type the PATH and NAME (no file extension)
       of the database you want to switch to, or create.
       The current database is closed.  If the path is valid, the
       next one will be opened.  If not, BlueBook defaults.

       Example:   C:\Docs\Letters   {go to "Letters" in "Docs"}

       ----------------------------------------------------------
       Note:  For technical reasons [memory, and the need to keep
       some "slack"], File/Next as presently implemented does NOT
       recognise zip-compressed databases.

       If you are using zip compression you should avoid using
       File/Next and set up a "metabase" instead (see Section
       7.7), accessing compressed databases from a "higher level"
       record via BBZip.Bat (rather than running BlueBook.Exe
       directly) - see "Zipping.Doc" for details on BBZip/BBPull.
       ----------------------------------------------------------

7.4    Integrated backup

       You can back up the currently open database from within
       BlueBook.  Click File/Backup, and enter the DESTINATION
       drive and directory.  The backup file(s) get the same name
       as the database, so DON'T enter a file name: just a path.
       Make sure you choose a DIFFERENT directory (because the
       file names are the same).

       Example:   C:\Docs                 { cf. example above }

       If you have PKZip/PkUnZip.Exe in your Path, you can choose
       to have backups zip-compressed.  Zipped backups are given
       the extension ".ZBK", eg. "Letters.ZBK".

       ----------------------------------------------------------
       IMPORTANT:  For technical reasons, when creating a zipped
       backup, BlueBook does not run PKZip directly.  Instead it
       runs a DOS batch file (BBZIPBAK.BAT) which it must be able
       to locate, either in the current directory or your PATH.
       ----------------------------------------------------------

       If you don't have these programs to hand, or you choose
       UNcompressed, File/Backup does a straight DOS copy to the
       destination directory - no renaming.

       ----------------------------------------------------------
       Note - ".ZBK" compressed backups are logically "different"
       from the ".ZIP" compressed databases that BBZip.Bat makes.
       In reality, not: only the extension is different.  But it
       makes life easier if you treat them as different, and keep
       ".ZBK" backups purely as backups.  Just a tip.
       ----------------------------------------------------------

7.5    Making and printing database listings

       This version of BlueBook offers basic listing functions
       only, in one of two fixed formats: either optimised for 
       least size, greatest readability; or for constant field
       positioning.  In the first case, all fields are output 
       unless empty, including joins (nul fields are suppressed).
       In the second case, ALL fields are output, empty or not.
       The first case is the default.  To toggle constant field
       positioning ON, set CompactListings=NO in the BlueBook.Ini
       file.

       Output is plain ASCII text, sent to printer or disk.

       To create listings of the current database, click
       File/Text.  A floating window appears, with buttons to
       Make, View, Print, and Erase.

       MAKE generates a file on disk of either the current item
       List or the whole database.  When asked, click Item or
       Full.  Listings go to the same directory as the database,
       as a file with the same name but an extension of ".LST".
       New "makes" overwrite old for any one database.

       VIEW uses BBView.Com to display a listing for the current
       database on disk [file "<DBasName>.Lst"].

       PRINT is the same as MAKE, except that the listing is sent
       to the printer (device PRN:), not the disk.

       ERASE deletes any listing file for the current database.

       ----------------------------------------------------------
       TIP:  If you want prettier listings, use Export to create
       a comma-delimited file of data (NOT IN FREEWARE VERSION),
       and use a word-processor to import, format and print that.
       (You'll probably need to check "Include Field Names?".)

       TIP:  The "ListingMargin" line in the BLUEBOOK.INI file
       can be adjusted to force a margin (default: 4 spaces).
       ----------------------------------------------------------

7.6    Copying, Renaming and Erasing databases

       There are no built-in commands to copy or rename a 
       database.  You can copy a database to another directory
       with File/Backup, or use the DOS commands on the THREE 
       files in a common directory with a shared name that make 
       up a database.  For example:

           COPY  C:\BLUEBOOK\TODO.BB*  C:\MYDATA   <Enter>
           REN   C:\BLUEBOOK\TODO.BB*  2BDONE.BB*  <Enter>

       You CAN erase a database from within BlueBook, using
       File/Erase.  Don't confuse this with File/Text/Erase,
       which deletes a LISTING file ("<DbasName.LST").

       File/Erase prompts for confirmation.
